T all whom it may concern:

Be it known that I, CLAEs RYDEN, a citizen .of the United States, residing at (-ranston, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Winding-Machines, of which thefollwing is a specification. 4 i r My invention relates to improvements in winding machines and particularly to the traverse-mechanism therefor.

The object of my. improvement is to provide a traverse-mechanism capable of minute I adjustment for difierent lengths of traverse or throw of the winding-guide and particularly designed to insurea more constant speed of traverse of. the guide through out the full extent of its movement to insure an accurate and precise disposition of the separate convolutions or windings of material. The device is particularly intended for machines used for winding wire in manufacturing coils for electrical purposes where aregular and uniform relation of the windings is most essential. The invention is fully described in the following specification, illustrated by the accompanying drawings, in which like letters of reference designate like parts. i

In the drawings :Figure 1 isa front leration of a winding machine showing my new traverse-mechanism applied thereto; Fig. 2 is a detail view of the rocker a rm of the traverse-mechanism; Fig. 3 is a side view of the same; Fig. it is a view of the traverse-arm connected with the traverseguide; Fig. 5 is a side view of the same; Fig. 6 is a sectional view of the link-connectingmeans of the traverse-mechanism taken on the line a-a of Fig. 4, lookingin the direction indicated by the arrow g; Fig. 7 is a diagrammatic view of the principal elements of .the traverse-mechanism illustrating its improved method of operation.

Referring first to Fig. 1, B designates the frame of a usual type ,of winding machine. having bearings forthe horizontal Windingspindle Z) and cam-shaft 0. Mounted on the shaft 0 is a traverse-cam C which is rotated throughdriving connections illustrated at D, and including a driving-pulley d, but not here shown in detail. Secured .to the front side of the frame B is: a bracket E, formed with an arm 6 reaching in towardthe cam C. At the end of the arm 'e is a bearing the, sleeve p e: for the stud" or rocker-shaftf which carries the traverse rocker-arm G. 'Refer r1ng to Figs. 2 and 3, the arm G is provided with a hub 9 made integral w th'or secured to the shaft f and formed w th a depending arm 9 having a boss or hub g at 1ts lower end. Projecting from the hub g? is a pin 1. on which is rotatably mounted a roll groove 2 of the traverse-cam C. e U rocks the arm G through the roll j and the motion derived therefrom is transmitted-tothe traverse-guide from an upwardly extending arm or lever vK. This latter is preferably formed as a separate piece constructed of sheet-metal and attached to the arm G. Any convenient means for attaching the two .arms G and K together might be used, and as here shown the arm K is mounted on a projecting portion of the shaft 7 with its lower end is fitted to inclose :1. turned down portion 9? of the hub 9*. Suitable pins vor screws Z secure the arm K against the hub 9 so that the parts G and K move together as one element.

Referring again to Fig. 1, the bracket E is formed with an upwardlv extending arm 6 having a hub 0 at its upper extremity. Extending from the hub e is a rod M arranged parallelwith the winding-spindle b. The outer end of-the rod M is supported in a bearing 7:, which surmounts a vertical arm N secured to a horizontalrod O. The rod 0 projects from a boss e on the side of the bracket E and is held in place by a screw 6. Mounted to slide on the rod M is a sleeve p which-carries a pivoted arm R to which is attached the winding-glide 1' adapted to bear on the winding-spindle b and to swing upward therefrom as the winding is built up on the spindle. Surrounding and secured thereto by the setscrew .sis a sleeve or bushing S. F astened t0 the sleeve S by the screws t is a depending plate or arm.T which I term the traverseguide arm. The lower edge of the arm T is fitted to slide in a longitudinal slot 0 formed in the red 0, see Figs.4 and 5.

The rocker-arm K is formed with a longitudinal slot -70 and the traverse-guide arm T is provided with a similar slot 2%. Extending between the two arms K and T is a link arranged with its terminal connectingmeans adjustable in the slots is and t. 1 Referring to Figs. 4, 5 and 6, the right- E the inner face of the arm T and its outer end is threaded to receive a nut v. Interposed between the nut 2) and the arm T is a washer W formed with a spline or key w which is fitted to the slot t to' keep the washer from turning. Projecting fromthe periphery of the washer W is a finger or pointer w having a beveled straight-edge w adapted to register with the graduations t of a scale running alongside the slot 25. The end of the pin a is scored with a peripheral groove a into which is sprung a split-ring a that abuts the end of the stud V and holds the pin in place. By tightening the nut '11 against the washer .VV the latter binds the head '0 against the arm T to hold the stud V in position in the slot t. By loosening the nut the stud can be adjusted up an down in the slot.

The connection of the opposite end of the link U with the arm K is made with 'practically the same arrangement. Projecting from the end of the link is a pin a: which extends through a' stud y fitted to the slot is. Sprung into a groove m. at the end of the pin .10 is a split-ring .00 which holds the pin in place in the stud. Extending upwardly from the rear end of the stud j y is an arm Y at the end of which is a second stud y also projecting through the slot is and carrying a nut 3 On the stud y is a-washer Z similar in form to the washer W and having a key '2 and index pointer 2. The pointer 2 can be adjusted along the graduations if when the nut :1 is released, and the study is normally held in its adjusted position by tightening the nut against the" washer Z. The purpose of the extension or arm Y is to raise the washer Z above the pin :22 to prevent it from interfering with the hub g of the rocker-arm-G when the end of the ljnk U is adjusted to a point adjacent the axis of the arm. That is to say, this arrangement allows the pin an to be slid down on the arm K to a point close to the axis of .the arm without causing the washer Z to strike the hub 9. To increase this clearance the hub 9 may be cut away at g, as illus-' trated in Figs. 2 and 3.. The graduations on the arms K and T are so related that when the pointer a is set at a certain mark on-its scale and the pointer w adjustedto register with the correspondin .mark on the arm T both ends of the link will be at the same height above the axis of the arm K. In

' 50 other words, the link U will be in a horizontal position, or level. It'is this feature of maintaining the link U level or substantially parallel with the line of movement of the winding-guide which provides for a 5 more uniform speed of traverse of the scribed. The cam G acts through the guide irrespective of its extent of traverse, as hereinafter more fully explained.

The operationof my improved device isas follows: Referring to Fig. 1, after it has been determined what extent of traverse of the winding-guide r is to be used to wind the package of yarn or coil of wire to the dimensions required, the pointer a is adjusted to the proper mark on the scale of the arm K, the graduations being preferably designated by characters or. figures, not here shown. The pointer 10' is then adjusted to the corresponding graduation on thescale of the arm T to insure a level position of the link 'U. The nuts 1 and 'v are then tightened to hold the link U in place on the arms K and T while allowing its ends to swivel on the pins u and w. The machine is now ready to operate and when power is applied through the drivingulley d the winding-spindle b and cam are rotated with the proper ratio of speed, as provided for by a system of gears or other intermediary mechanism, not herein shown or deroll j to impart an oscillatory motion to the-arm K which is transmitted through the =link U to cause reciprocation of the arm T which slides in the slot 0 of the rod 0. The arm T being connected to the sleeve 2 causesthe latter to slide back'and forth on the rod M and as the sleeve 10 carries the arm R and winding-guide 1' the latter willbe reciprocated to traverse along the winding-spindle Z). The movement of the rocker-arm K as imparted by the cam C is constant, but its range of action can be regulated, as before described, through adjustment of the point of connection of the link U toward or away from the axis of the arm. The amplitude of oscillation of the point of connection of the link on the arm controls the extent of traverse of the guide 1' and thus the length of the layers of windings can be regulated withincertain limits. I am aware that it has heretofore been, proposed in winding mechanisms to regulate the extent-oftraverse of the winding-guide by adjustingits point of connection on the oscillating arm from which its reciprocatory Fig. .7 of the drawings which is a diagram- 12.3

matic representation of the usual mechanism for reciprocating the winding-guide from an oscillating arm to allow for adjustnient of the length of traverse of the guide.

The axis on which the oscillating rocker-arm 1 link .on' the arm,.when the latter is in midlink is adjusted as abpve zo onstrate d' b are 12 to the poin but this' is not of.

pivbts is designated by 2, and the extremes of movement of. its upper end are shown at 3 and 4., while 5 represents its mid-position. The full lines 6, 7 and 8 represent 5 or connection between thear'mand the ide I and the two-extremes of traverse o the guide are shown at 9-and 10 and the fund- -position at 1 1. It will be seen that theextreme upward point of connection 5 of the position, lies in the same horizontal plane with the=point of connection .9, 10 or 11- of the link with the guide,\this being the usual en the connecting arrangement. New; wh

described to transmit the maximumextent of throw of the arm to the guide the speed of traverse of the latter will remain substantially constant from 9 to 10- and back again. This, is demgu de as the pointfi moves to 5 and the slight retardation therein from 5 to 6, due to the a0 change in angularity of the link 7 on account of the arcuate p'ath of travel of the point 4, is practically imperceptible. When, however, the point 4 is adjusted toward the axis 2 of the rocker-arm to shorten the throw of the guide this change inthe angularity of the link with respect to the horizontal line 7 becomes more marked and consequently there is a considerable variation in the speed of traverse of the winding-guide.

at This change is illustrated graphically by the dash lines 14, 15,16 which represent the positions of the link at the two extremes of os- ,cillationof the rocker-arm and also at the mid-positionof the latter. The. positions .45 of the thread-guide at these intervals are des ignated respectively 17, 18,19; The opposite connecting-point of the link onthe rocker-arm at one extreme resented at 20; at 21 at the other extreme;

and at 22 when therocker-arm is in midposition. Assuming that the point of connection of the link with the guide remains in the horizontal plane of the line 7, which is the usual arrangement as .before explained, and that the opposite point of coni nection 3 is moved down on the rocker-arm to 20 to effect a shorter traverse of the guide, then the following variation in speed of the guide must take place: As the point 20 moves to 22 the speed of the guide will be accelerated, while as the point 22 moves to 21 the speed of the guide will be decreased. This is shown graphically by the disparity in distance between the points 17 and 6 19'"as compared to .the distance between the the link rocker-arm, as the point of connection oflthe as shown by 'the lines 23 y the fact thatthe point 11 is" slight as the of traverse is reppoints 19 and 18. Y ln other. words, ing-guide will move a greater distanceduring-the first half of the. oscillation ofi'the link moves from 20 to 22," than during the last half, when the point change in'speed of tlre'guide fromohe end of the traverse to the other'aflects the laying of the windings as follows: It will be understood that the -ratio of speed between the the wind- 22 moves to 21,}. and 24:. 1 This.

winding-spindle and guide remains constant afteronce being adjusted to give the proper disposition ofthe convolutions or turns of the windings in relation to each other. For instance, in winding wire into electrical coils the speed ratio of-the spindle and guide are so ad usted that the turns 'orhelices of; the wire, will he laid contiguous or one close;

to another throughout all ofthe layers of the coil, Now, if this ratio is fixed so that the helicesv of wire position toeach other of the traverse of the 19 in Fig. 7, then,

during the first part guide, orvxfrom 17 to with the arrangement of are" laid 'in close juxtatraverse-mechanism above. described, when the guide continues itstra'versefrom 19 ta 18 the turns of the wire willkhe, crowded together so that they cannot be deposited in a smooth layer. Putting it another way, since there are the same number of turns or .con volutions of the wire from 17 to 19: as from 19 to 1 8 the turns in layer must be farther apart or wound more open than the turns in the last part.

To return to the practical phase of the subject, it has been demonstrated that with the usual arrangement of mechanism adapted to wind with. the traverse of the guide adjustable in length to suit different commercial requirements, the laying of the turns or convolutibns in the winding cannot be accurately controlled to give them a uniform disposition, that is an exact spacing, throughout each layer. This is a most important consideration and my present improvement is especially designed to meet the requirements of accurate uniform winding. With the novel arrangement herein disclosed it is proposed to adjust the point of con nec tion of the link U adjustment of the point of the first,portion of a connection of the link on" the rockerfarm.

In brief, the connecting-link between the rocker-arm and the guide 'to provide for maintaining it always in a horizontal position whatever the relation of its point of connection to the axis of the rocker-arm may be, and hence the speed of traverse of the guide is not open to the influence of changes in angularity of thelink.

isyextremely simple in structure and mode of operation, but not-- My'-- new device withstanding this, it has manifest advantages as above pointed out. As "before is 230 arranged as i it is most important in such work that the windings be regular and uniform throughstated, it is particularly adapted 'to ma-' 1. In a winding machine, the combina 1 two arms, means to adjust said on both chines employedifor winding wire or other conducting material into electrical coils, and

out the whole coil. Heretoiore it hasbeen extremely diflicult to obtain this uniformity,- particularly with very fine wire, and'my im-' provement is therefore of rutmost importance as applied to this field. It will be understood, however, that my new traversemechanism is equally well ada. ted for other purposes and to other'types oj m'achines than that here shown. v

Various modifications might be made in the formand arrangement of my, new device without departing from the spirit or scope of'the invention,

Therefore, without limiting myself to the exact construction shown and described,

what I claim is tion with the winding-spindle and traverseguide, of an oscillating rocker-arm for reciprocating the guide, a corresponding arm attached to the guide, a llllk connecting the arms with respect to'the axis of oscillation of the rocker-arm, and index devices on .both arms for indicating the extent of ad-' justment at each end of thelinkto provide for an accurate setting'thereof'at both of its ends to insure a constant speed of traverse of the guide and a uniform spacing of the coils of winding.
